TO ALL WHOM 'IT MAY CONCERN:

Be it known that I, JOHN D. BRUN NER, of Doylestow'n, in the county of Bucks, and in the State of Pennsylvania, have invented certain new and-useful improvements in Shaft-Couplings; and do herehy declare that the following is a full, clear, and exact description thereof, rei'crencebeing had to theaccompanying drawings and to the letters of reference marked thereon. In the annexed drawings, making part of this specification -A represents a metallic car, which is secured to the under side of the front axle of the vehicle bymeans of the loop B, with its nuts upon each of its ends. This bar is provided with a slot oropening, 0 0, cut through it from top to bottom, said slot running lengthwise of the bar. The forward end of this hair is curved, as seen, and prov'idedwith a squ'areshoulder, from X to X. At thedo wer end of the shoulder X, a semicircular groove is cutncross the bar for the end of the shaft-iron or a bolt to rest in. E represents a bolt, which passes through the opening o-from the upper side of thebarand is provided withla h'eacl,-D, which said head is provided with a square shoulder and a semicircular groove to correspond with those of the bar A. C represents a shaf't iron, which iseither provided with a loop or with two jaws at its rear end, through which a bolt may pass to secure it to theb'ar A. A loop is here represented, the cross-bar of which at the end of the shaft-iron is made in-proper shape to'fit in the circular groove formed in the head 'ofthe nut and the shoulder of the bar A. The cross-bar of the loop .of the shaft-iron is securedin the circular groove mentioned by forcing up the shoulder, of the head D as near to the shoulder of the bar'A as it will go, and then tightening the nut on the lower end of bolt E. The bar a of the loop may be too large to allow the shoulders to meet, but the head will fit with its groove against it on one side, and may be moved up to it, as fast as it Wears, to prevent any rattling. This arrangement of devices forms a cheap and simple shaft-coupling, while it makesa complete anti-rattler.

Having thus fully'descrihed my invention, what I claim as.new, and desire to secure by Letters Patent, is

The ,bar A provided with the slot 0, as herein described, when usedwith the head D and bolt E, in the manner and for the purposes specified.

In testimony that I claim the foregoingI have herennto set my hand this twelftlnday of March,'1867.
